Over two thirds of Brits (68 percent) plan to buy at least half of their gifts online this Christmas, says Webroot.

Research by the internet security company revealed that the number of shoppers intending to purchase gifts online has increased by 46 percent since 2007.

Furthermore 12 percent said they use a public Wi-Fi networks when purchasing gifts online, even though this can be a security risk.

Webroot also said that 52 percent use search engines to find gifts while 38 percent automatically trust all links of the first two pages of results, despite the threat of malicious links appearing.

The research also revealed that only four percent of web users will not buy online because of potential security risks.

Webroot said it had seen an increase in phishing Trojans - which can steal credit card numbers, passwords and other information - in the months leading up to November, just as people begin thinking about buying gifts.

"Remember that hackers don't take a holiday; be aware of how they operate and protect yourself," said Mike Kronenberg, chief technology officer of Webroot's Consumer business.
